Ender 3 Pro Flexible Filament Attachments

thingiverse

After finding Issues with the stock Ender 3 Pro getting tpu stuck and not extruding, I found this tube and bracket to help line up the filament path so that the filament has less resistance going to the hot end. The tube is tensioned with a small rectangle of cut-up raft, which I suggest printing one of the prints with. The bracket hasn't proved to do much for me, as it was just the test piece before I found success with the tube. Notable Settings in Cura when printing tpu: Infill: 100% Hot End Temp: 220C (More specific to your tpu) Bed Temp: 70C Print Speed: 30 mm/s Retraction: Disabled Fan Speed: 60% Also making sure to have some sort of extra build plate adhesion for me it was glue stick.
